[oracle@eric ~]$ export ORACLE_SID=cup

[oracle@eric ~]$ sqlplus / as sysdba

Connected to an idle instance.

SQL>startup-----不会直接启动所有可插拔数据库，如需启动所有可插拔数据库，执行命令：alter pluggable database all open

ORACLE instance started.

Total System Global Area 767557632 bytes

Fixed Size 2929112 bytes

Variable Size 574623272 bytes

Database Buffers 184549376 bytes

Redo Buffers5455872 bytes

Database mounted.

Database opened.

停止根容器：

SQL>shutdown immediate

Database closed.

Database dismounted.

ORACLE instance shut down.

查看是否创建了CDB，如果有显示名字:

SQL>select name,cdb from v$database

NAME CDB

--------- ---

CUP YES

SQL>show parameter service

NAME TYPEVALUE

------------------------------------ ----------- ------------------------------

service_namesstring cup

查看容器名字，其中有3个容器：根容器、种子容器和自己创建的容器:

SQL>select con_id,name from v$containers

CON_ID NAME

---------- ------------------------------

1 CDB$ROOT---根容器

2 PDB$SEED---种子容器，只可读

3 TEA ---自己创建的可插拔数据库

SQL>select file_name from dba_data_files

FILE_NAME

--------------------------------------------------------------------------------

/oracle/app/oradata/CUP/datafile/o1_mf_system_bch07kvz_.dbf

/oracle/app/oradata/CUP/datafile/o1_mf_sysaux_bch020oo_.dbf

/oracle/app/oradata/CUP/datafile/o1_mf_undotbs1_bch0d2on_.dbf

/oracle/app/oradata/CUP/datafile/o1_mf_users_bch0d15n_.dbf

SQL>select file_name from cdb_data_files

FILE_NAME

--------------------------------------------------------------------------------

/oracle/app/oradata/CUP/datafile/o1_mf_system_bch07kvz_.dbf

/oracle/app/oradata/CUP/datafile/o1_mf_sysaux_bch020oo_.dbf

/oracle/app/oradata/CUP/datafile/o1_mf_undotbs1_bch0d2on_.dbf

/oracle/app/oradata/CUP/datafile/o1_mf_users_bch0d15n_.dbf

创建公共用户：

SQL>create user c##eric identified by gao

User created.

SQL>conn c##eric/gao

ERROR:

ORA-01045: user C##ERIC lacks CREATE SESSION privilegelogon denied----没有权限，我们可以单独给其赋予权限，也可以给其指定角色。

Warning: You are no longer connected to ORACLE.

SQL>conn / as sysdba

Connected.

SQL>grant dba to c##eric container=all---给其DBA角色，角色范围覆盖所有的容器

Grant succeeded.

SQL>conn c##eric/gao

Connected. ---连接成功

切换容器：

首先启动自己创建的容器数据库：

SQL>alter pluggable database tea open ---首先启动PDB数据库

SQL>alter session set container = tea

Session altered.

SQL>show con_name ---查看当前所在的容器名

CON_NAME

------------------------------

TEA

关闭可插拔数据库：

SQL>alter pluggable database tea close immediate

Pluggable database altered.

和普通实例一样的连接。 指定ORACLE_SID 以后可以使用OS认证，也可以使用密码进行连接。

[oracle@Ora12c /]$ echo $ORACLE_SID

cndba

[oracle@Ora12c /]$ sqlplus / as sysdba
